WOODWORKlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 717,454, dated December30, 1902. Application filed September 15,1902. Serial No. 123,513. (Nomodel.)

To all whom it may concern:

Be it known that I, JOHN N. ROSEN, a citi-" as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to woodworking-machines; and its object is toprovide acombination-machine adjustable at will to work as a joiner orplaner. I

Withthe above and other objects in view, which will readily appear asthe nature of the invention is better understood, said inventionconsists in certain novel features of construction and combination andarrangement of parts, which will be hereinafter fully described andclaimed, and illustrated in the accompanying drawings, in which- Figure1 is aside elevation of the machine as adjusted to operate as a joiner.Fig. 2 is a longitudinal section of the same. Fig. 3 is a top plan view.Fig. 4 is a cross-section on the line 4 4 of Fig. 1. Fig. 5 is anelevation looking toward the opposite side of the machine from thatshown in Fig. 1 and showing the parts adjusted to adapt the machine tooperate as a planer. Fig. 6 is alongitudinal section of the same.section on line 7 7 of Fig. 5. tail View of the chip-breaker.

, Referring now more particularlyto the Fig. 8 is a dedrawings, 1represents the frame of the ma chine, provided at top with work-tables 2and 3, each of which is mounted upon a sliding carriage 4, which may beof any of the ordinary constructions, the two work-tables thus mountedbeing adjustable toward and from the center of the frame. Eachwork-table is independently adjusted upon its carriage through themedium of an adjusting-screw 5, and is provided withdownwardly-extending inclined lugs 6, which engage inclined guides 7 onthe carriage, whereby the tablelm ay be longitudinally adjusted on thecarriage as occasion demands.

The table 2 is provided with the usual workgage 8.

Fig. 7 is a cross .or supports carry the bearings in which'are ,mountedthe rotary cutter-head 11 and the feed rolls 12 and 13. As shown, thebearings 12and 13' of the two feed-rolls 12 and 13 are removably mountedin slots in the side plates 01' supports and are held seated therein byrods 14, which are connected to coil-springs 15, which exert pressure onthe rods to hold the bearings in place. In addition also either one orboth of the bearings may be held in place by set-screws 16, mounted onthe said adjustable central frame.

A bandpulley 17 is revolubly mounted upon one side of the adjustablecentral frame and carries a spur-pinion 18, meshing with a pair ofspur-gears 19 19, journaled adjacent thereto and having formed thereonbevelgears 20 20, which mesh with corresponding gears 21 21 on the lowerends of two vertical shafts 22 22', which shafts are provided at theirupper ends with worm-gears 23 23, which mesh with worm'wheels 24 24 onthe extended ends or shafts of the feed-rolls 12 and 13.

The shaft or extended end of the cutter 11 is provided with two pulleys25 25, the former having passing therearound a belt A, designed toleadfrom a drive-shaft, (not shown,) while the latter is connected to thebandwheel17 by a belt 26. A shifting lever 27, adj ustably mounted uponthe adjacent side of the frame 1, is pivotally connected at one end to abracket or arm 28, pivoted upon the contiguous side support of thevertically-adjustable central frame, and this arm carries atightener-pulley 29, which bears upon the belt 26 and by means of whichthe belt may be maintained at the desired tautness or tension andadjusted to start or stop the wheel 17. The opposite side plate orsupport of the vertically-adjustable central frame is provided with amark or indicator 30, cooperating with a scale 31 on one of the guides10, whereby when the adjustable frame is moved up or down the positionof the cutter and feed rollers maybe determined and the parts set at theexact adjustment to suit the work to be done.

The two plates or side supports 9 of the central frame are connected bya cross-bar 32, below which is arranged a cross-bar 33, connected to thesides of the frame 1. Journaled in this cross-bar 33 are screw-shafts34, which work in threaded openings in the bar 32 and are provided attheir lower ends with gear-wheels 35, meshing with gear-wheels 36 on anoperating-shaft 37, journaled in the sides of the frame 1 and providedat one end with a crank-handle 38.

One of the side supports 9 of the central frame is bifurcated orrecessed to receive the shaft 37, thus allowing said support to bevertically adjusted without interference therewith.

By the operation of the shaft it will be seen that motion will betransferred to screw-shafts 34 to raise or lower the central frame andthe cutting, feeding, and driving elements of the machine.

A central table 39 is mounted to slide on guides 40, fixed upon theinner surfaces of the sides of the frame 1 and is adjustable toward andfrom the center of the frame through the medium of a screw-shaft 41, theguides 40 being inclined so as to cause the central table to moveupwardly when adjusted toward the center of the frame and moveddownwardly below the work-table 2 when adjusted away from the center ofthe frame.

A rod or bar 42, fixed at its ends in the side supports 9, extendsparallel with the feedroll .12 and forms a support for a swinging frame43, consisting of curved arms 44, journaled at their inner ends uponsaid rod and provided at their outer ends with sockets or openings 45.Pivoted between and to these arms is a segmental-shaped chip-breaker 46,which is provided upon its convex side with longitudinal sliding bolts47 to engage said sockets or recesses 45. This chip-breaker is alsoprovided at opposite sides with lugs 48, carrying set-screws 49, wherebythe chipbreaker when adjusted to cover the cutter 11 may be adjustedwith relation thereto, as hereinafter described.

Figs. 1 to 4, inclusive, show the parts adjusted to adapt the machinefor use as a joiner, from which it will be seen that the central frameis depressed and the tables 2 and 3 adjusted inwardly, so as to coverthe feed rolls 12 and 13 and expose only the cutterhead 11, also that inthis position of the parts the center table 39 is at the limit of itsoutward and downward movement, while the frame 43 is swung downwardbelow the table 2 and the chip-breaker 46 is swung inwardly upon saidframe 43, so as to occupy a folded position between said frame and theinner end of the table. The outer ends of the arms 44 rest upon thecenter table 39, whereby the frame 43 and chip-breaker are supported. Itwill be readily observed that this arrange ment of the parts of themachine adapts the same for operation as a joiner.

In adjusting the parts to adapt the machine to serve as a planer thegage 8 is removed from the table 2, the tables 2 and 3 moved outwardlyor away from each other to expose the upper portion of the centraladjustable frame, and the latter is then elevated through the medium ofthe crank 38, shaft 37, and connecting-gearing to raise the cutter-head11 andfeed-rolls 12 and 13 above the level of the tables 2 and 3. Whenthis has been done, the frame 43 is swung upwardly and over thefeed-roll 12 and the chip-breaker 46 reversed or swung over, so as tocover the cuttingcylinder 11, and then looked in such adjusted positionby forcing bolts 47 outwardly to engage the sockets or recesses 45 inthe arms 44. The set-screws 49 will then rest upon the bearings of thefeed-roll 13 and enable the chip-breaker to be adjusted properly withrelation to the cutter-head 11. The center'table 39 is then adjusted bymeans of the screw 41 to the limit of its inward movement to lieimmediately beneath the roll 12, and then the work-tables 2 and 3 areslid inward to cover the space on opposite sides of the central frame,thus adjusting the feeding and cutting mechanism to enable the machineto be used as a planer.

From the foregoing description, taken in connection with theaccompanying drawings, it is thought that the construction, mode ofoperation, and advantages of my improved woodworking-machine will bereadily apparent without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details ofconstruction maybe resorted to without departing from the prinoiple orsacrificing any of the advantages of this invention.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is
